BUTTON.

SPECIFICATION forming part of Letters Patent No. 324,832, dated August 25, 1885.

Application filed June 29, 1855. (No model.)

T 0 all whom, it may concern..-

Be it known that 1, WILLIAM H. GIFFORD, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful lmprovementsin Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to an improvement in buttons, and more particularly to that class of buttons which are commonly termed linkbuttons, and it consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a face View of the button in position on a cuff. Fig. 2 is a back view of the same. Fig. 3 shows the button with the bar released, ready to be adjusted to the cuff, the bar being shown in section.

A represents the back of the button. It is preferably oblong or oval in shape, but may be made in any desired shape to suit the fashion or the taste of the purchaser. It is also preferably curved to suit the contour of the cuff, as this shape tends to keep the ends of the back in close contact with the surface of the cuff, but may be constructed flat, if desired.

Two posts or standards, B and O, are firmly secured to the back near the ends. The post B is bifurcated, and one end of the lock bar D is hinged or pivotally secured between its branches by a rivet or pivotal pin. The post 0 is provided with a notch, 0, near its end, preferably facing the post B, and the portion of the post between the notch c and its extreme end is beveled, as shown at c.

The lock-bar D is hollow, and preferably curved to conform to the back, and is provided with a longitudinally sliding plunger or latch, d, located within it. The plunger (1 is actuated by a spring, E, located within the lock bar between its hinged end and the end of the plunger, the tension of which tends to force the plunger toward the locking end of the bar D. A small operating pin,

stud, or screw, e, is secured in the back of the plunger, and is allowed a limited movement in the direction of the longitudinallysliding movement of the plungerin an elongated closed slot, F, formed in the back of the bar D.

The bar D is further provided with a slot or perforation, f, in a position to receive the end of the post 0. The position of the pin or stud e is such relatively to the slot F that when the pin 6 is in contact with the end of the slot toward the locking end of the bar D the end of the plunger d rests partially over the perforation f in a position to engage the end of the post 0 when the bar is pressed into closed adjustment. The end of the plunger cl which engages the end of the post-(J is beveled, as shown at d, and when the beveled end of the post 0 comes in contact with the beveled end of the plunger it acts as a cam in sliding the plunger longitudinally out of its path. As soon as the notch 0 comes opposite the end of the plunger the latter is promptly thrown into engagement with the notch by the action of the spring E, and the bar D is thereby locked securely to the button.

To release the bar, the operating pin 6 is forced backwardly from the end of the slot, thereby sliding the plunger out of engagement with the notch, and leaving it free to swing away from the post 0.

Since the button is conveniently longer than it is wide, and the posts B and 0 set near itsedges, in order to obtain the maximum length of lock-bar with a minimum weight and size of button, I find it advantageous to have the button-holes made in. the cuffs in the opposite direction from thatin which they are commonly made, by which construction the button-holes will be completely covered, and give the cuff a much. neater appearance than is possible in the common form, without.

a considerable extent of button beyond the posts.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-- The combination, with a button-back having notched near its outer end, of a hollow locktwo rigid posts secured thereto, one post being In testimony whereof I have signed this specification in the presence of two subscribbar hinged to one post, and a spring-actuated ing witnesses. latch or bolt located wholly within said hollow lock-bar, and provided with a projection that extends through an elongated slot in the lock-bar, substantiallyvas set forth.
